THOMAS W. WORLEY, OF NEW YORK, N. Y.

NURSING-BOTTLE.

SPECIFICATION forming part of Letters Patent No. 595,986, datedDecember-21,1897. Application filed February 12,1897.v Serial No.623,069. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS W. M. Won- LEY, of New York city, in thecounty and State of New York, have invented a new and ImprovedNursing-Bottle, of which the following is a full, clear, and exactdescription.

vThis invention relates to infants nursingbottles, and has for itsobject a nursing-bottle on which the rubber nipple may be held withoutdanger of its coming off and allowing the contents of the bottle toescape.

A further object of the invention is to pro vide such a bottle of veryfew parts, which can be cheaply made and in whichthe nipple is securelyheld directly on the bottle-neck by a device which engages only itsouter surface, so that no metal or any other substance liable to makethe milk sour will comein contact with the milk.

The construction and arrangement of the parts will be first described,and then particularly pointed out in the appended claim.

Reference is to be had to the accompanying drawings, in which Figure 1is a side elevation of the bottle proper formed 1n accordance with thyinvention. Fig. 2 is a sectional view of a cap employed to secure therubber nipple upon the bottle-neck shown in Fig. 1. Fig. 3 is a top planView of the same, and Fig. 4: is a partial section and partial elevationshowing the nipple secured in place.

The nursing-bottle 1 may be of any desired form as to its body portion.Its neck 2, however, is provided near its upper end with an externalscrew-thread 3, which terminates at a point some distance below theupper edge of said neck, an outwardly-projected annular bead 5 at .suchedge, and a reduced portion 4, joining said bead with the threadedportion.

The fastening-cap, which may be made of metal, hard rubber, or the like,has a threaded portion 6, adapted to engage the screwthread 3 of thebottle-neck, and above the threaded portion 6 the cap is enlarged, as at7, so as to form a space or chamber between it and that portion of thebottle-neck (the bead 5 and reduced portion 4) which it incloses. In thetop 8 of the cap is formed a central opening whose diameter'is less thanthe diameter of the bead 5, fora purpose now to be explained.

The nipple 9 (shown in Fig. 4) is first applied to the bottle-neck, withits lower open end expanded over the bead 5 and drawn down until it isstopped by the screw-thread to cover the reduced portion at, to which itwill closely adhere, owing to the elasticity of the rubber. The cap isthen inserted over the nipple, as shown in Fig. 4:, and is screwed downon the thread 3 until its top engages the lower end of the nipple 9 andpresses the rubber against the top of the bead. The chamber formed bythe enlarged portion 7 of the capallows for the expansion of the rubberbelow the cap, so it is possible for the cap to be screwed down verytightly upon the nipple.

-By the constructionabove described it is evident that it is practicallyimpossible to accidentally remove the nipple-from the bottle.

' As cases have been known in which the nipple has become separated fromthe bottle while the nipple was in the childs mouth and drawn into thewindpipe,causing choking,the usefulness of my improved bottle isapparent.

What I claim, and desire to secure by Letters Patent, is

As a new article of manufacture, the here- ,-in-describednursing-bottle, having its neck formed with a screw-thread terminatingat a point below its upper edge, and an annular bead at such edge, andby which a reduced portion is formed between said bead and thread, and acap having a portion formed with a thread arranged to engage the threadof the neck, an enlarged portion thereabove of greater diameter than itsthreaded portion, and a top which extends directly over said bead andwhich has a central opening of less diameter than the said bead, wherebysaid top may press directly down upon a nipple expanded over said bead,the enlarged portion of said cap allowing of free expansion of thenipple below the pressed part of the same, as and-for the purpose setforth.
